17 claims

Legal claims defining the scope of protection, as filed with the USPTO.

2

2. The electronic display of claim 1, wherein the signal routing circuitry of a first pixel of the plurality of pixels is configured to turn off the self-emissive element of the first pixel by shunting the pixel drive current to ground when the first pixel is the defective pixel.

3

3. The electronic display of claim 1, wherein the signal routing circuitry of a first pixel of the plurality of pixels is configured to turn off the self-emissive element of the first pixel by blocking the pixel drive current from reaching the self-emissive element of the first pixel when the first pixel is the defective pixel.

4

4. The electronic display of claim 1, wherein the signal routing circuitry of three adjacent pixels of the plurality of pixels are configured to turn off the self-emissive elements of the three adjacent pixels when at least one of the three adjacent pixels is defective.

5

5. The electronic display of claim 4, wherein the three adjacent pixels have self-emissive elements of three different respective colors.

6

6. The electronic display of claim 5, wherein the signal routing circuitry of the three adjacent pixels of the plurality of pixels are configured to shunt three respective pixel drive currents of the three adjacent pixels to ground when at least one of the self-emissive elements of the three adjacent pixels is defective.

7

7. The electronic display of claim 6, wherein the signal routing circuitry of the three adjacent pixels of the plurality of pixels are configured to block three respective pixel drive currents of the three adjacent pixels from reaching the respective self-emissive elements of the three adjacent pixels when at least one of the self-emissive elements of the three adjacent pixels is defective.

8

8. The electronic display of claim 1, wherein the signal routing circuitry of a first pixel of the plurality of pixels is configured to supply image data to the second self-emissive element of a second pixel when the pixel drive circuitry of the second pixel is defective.

9

9. The electronic display of claim 1, wherein the signal routing circuitry of three adjacent pixels of different colors of the plurality of pixels are configured to supply image data to respective self-emissive elements of three other adjacent pixels having the same respective colors when the pixel drive circuitry of one of the three other adjacent pixels is defective.

10

10. The electronic display of claim 1, wherein the signal routing circuitry of a first pixel of the plurality of pixels is configured to receive image data from the first adjacent pixel when the pixel drive circuitry of the first pixel is defective.

12

12. The method of claim 11, comprising determining a location of the defective pixel before determining the luminance difference.

13

13. The method of claim 11, comprising determining an additional defective pixel and shunting additional pixel data to be received by the additional defective pixel to ground based on the defective pixel voltage, wherein shunting the additional pixel data to be received by the additional defective pixel to ground comprises shunting one or more color components of the additional defective pixel to ground.

14

14. The method of claim 13, wherein the one or more color components comprise three color components.

15

15. The method of claim 13, wherein shunting the additional pixel data is based on selection of a select signal.

17

17. The article of manufacture of claim 16, wherein the non-transitory computer-readable media comprises instructions to adjust additional image data to be received by other nearby pixels of a same color component as the defective pixel.

18

18. The article of manufacture of claim 17, wherein the other nearby pixels comprise nearest-neighbor pixels of the same color component as the defective pixel.

19

19. The article of manufacture of claim 16, wherein additional image data associated with an additional defective pixel is adjusted by scaling the additional image data associated with the additional defective pixel to darken the additional defective pixel when the additional defective pixel is a defective bright pixel.

20

20. The article of manufacture of claim 19, wherein scaling the additional image data comprises scaling the additional image data to 0.
